SPECIFICATION forming part of Letters Patent No. 665.239, dated January 1, 1901.

Application filed July 28. 1900- Serial No. 25,170. (No model.)

useful improvements in car-doors, and more particularly to grain-car doors, although the door is adapted for use in connection with freight-cars of various description.

The invention relates more particularly to the class of doors usually provided upon freight-cars employed for the transportation of grain, which are known as grain-doors, and are designed when in use to close only the lower portion of the car-opening in each side of the car and when not in use to be raised to the top of the door-opening and swung back to a substantially horizontal plane, whereby the said opening is left clear and the door itself The intermediate hinge is provided with a bifurcated lower end which receives a pivot-pin for hinging the former to a bearing-bracket carried by the lower section of the grain-door. Means secured to the top of the car for suspending the door in a horizontal position and other details of construction will be more specifically hereinafter referred to, all of which are so arranged that when the car-door is vertically adjusted and brought to its horizontal position the door and its connections will swing entirely free of the car-door opening.

The invention further consists of the novel combination and arrangement of parts, hereinafter more specificallydescribed, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto annexed, and in describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, whereon like numerals of reference indicate corresponding parts throughout the several placed in an out-of-the-way position. views, and in which 75 Grain-doors of the above class now in gen- Figure 1 is a rear elevation of one of the eral use are commonly arranged to be vertiwalls of a car with my improved door concally adjustable upon a pair of stationary nected thereto.

Gonsea like view showing the door about to be ele- 8o quently when transporting other freight besides grain these guides frequently interfere with the storing of the freight in the car or are liable to become bent or injured in the loading or unloading of the freight or the jarring of the freight against the guides while in transit, thereby impairing or destroying the utility of the guides for use in connection vated.

use of the car for freight of any description or be itself injuriously affected by such use; and to this end the invention consists of a grain-door vertically adjustable by means of a pair of pivoted hangers connected at their lower end to an intermediate hinge secured to the upper section of the grain-door, which is so constructed that the sections will be hinged together below their abutting edges.

Referring to the drawings by reference-numerals, 1 denotes a portion of a freight-car, 2 the top, and 3 the floor thereof. The car is provided with the car-door opening 4, having the sill 5 and jambs 6. Arranged within the opening l is a grain-door, consisting of the upper section 7 and lower section 8, which are of the ordinary construction and provided on their rear face with the studs or braces 9,

10, and 11, respectively, and on their outer face with the hand-grip 12', consisting of a strip of suitable material extending across the lower section 8 and formed with a series of recesses, as indicated in dotted lines, as at 13.

Secured to the car at each side of the dooropening 4, near the top thereof, is a pair of supporting-brackets 14, each formed with a bearing-sleeve 15 to receive the pin 16, carried by the upper end of the hanger or link 17, having an oval-shaped slot formed in its lower end, as at 18. The hanger or link 17 extends below the top edge of the section 7 of the door and is pivotally as well as slidably connected to the section 7 by means of the bearing-pin 19 extending through the slot 18 and secured to the hanger or link by means of the split pin 20. The bearing-pin is form ed integral with the up er end of the elongated plate 21, secured to the section 7. The plate 21 is provided with a bifurcated lower end 22, surrounding the bracket 23, connected to the upper end of the section 8. The bracket 23 is provided at its lower end with a bearingsleeve 24, through which extends, as well as through the bifurcated ends of the plate 21, a bearing-pin 25 for hinging the two sections of the door together below the abutting edges thereof.

The reference-numeral 26 denotes a thimble-socket secured to each side of the dooropening at the bottom thereof and which is adapted to receive the boss 27 of the cornerplates 28, which are secured to each lower corner of the section 8 to prevent any lateral or longitudinal movement thereof when in a lowered position. To facilitate the entrance of the bosses 28 in the sockets 26, the former are somewhat tapered, as shown, and by this arrangement the section 8 is secured in a vertical position against the door-jambs.

For retaining the upper section 7 in position the top of the same has secured thereto a pair of plates 29, upon which operate the end of the hook 30. This hook 30 has one end formed with an angularly-disposed slot 31 for mounting upon a retaining-screw 32, secured to the door-jamb 6. In practice the hook 30 is elevated until the lower end of the slot 31 comes into engagement with the screw 32 and the opposite end of the hook is brought over and against the plate 29, the slotted end of the hook being then lowered until the upper end of the slot 31 is in engagement with the screw 32, thus securely clamping the section 7, as well as the section 8, in position.

For supporting or suspending the sections 7 8 in a horizontal position when swung clear of the car-door opening a downwardly-extending hanger 33 is provided and is formed with a bifurcatedupper end 34 and an offset 35, both of which are secured to a rafter 36 of the car by any desirable means. In the lower end of the hanger 33 is arranged an opening 37, having pivotallyconnected therein, by means of the pin 38, an outwardly-extending catch 40, provided with a thumbpiece 39. The catch 40 is adapted to engage the lower end of the section 8 and support the sections when swung horizontally.

The lower section 8 of the car-door is formed at the bottom thereof with a pairof openings 41 to permit of the insertion of a lever 42 to assist in raising the door, as shown in Fig. 4. These openings are closed by means of a sh utter or gate 43, pivotallyconnected to a bracket 44, connected to the inner face of the section 8, near the bottom thereof. The shutters or gates 43 are adapted to swing inwardly.

To raise the door from the position shown in Figs. 1 and 2, the lever 42 is inserted through the openings 41 and the sections elevated, causing the section 7 to assume a tilting position, the lever being removed and the sections elevated, by means of the hand-grip 12, until it assumes the position shown in Fig. 5, when the sections are swung inwardly and retained in a horizontal position by means of the catch 40 of thehanger 33. WVhen the sections are in this position, the upper edge of the section 8 rests against the brackets 14 and is supported on the bearing 45, formed integral with the bracket 14, and the section 8 securely held against movement in either direction. To lower the grain-door to the floor of the car, the lower edge of the section 8 is raised until it clears the catch 40, and it is then swung downwardly against the doorjambs, as shown in Fig. 5, the top of the section 8 beingthen pulled over and downward and the section lowered to the floor, during the travel thereof the section 7 assuming its normal position.

It is thought the many advantages of my improved construction of grain-car door to be swung entirely free from the sides of the car to prevent injury thereto can be readily understood from the foregoing description, taken in connection with the accompanying drawings, and it will be noted that various changes can be made in the details of construction without departing from the general spirit of my invention.
